I'm currently working on a custom level for NSMBU, a recreation of Green Hill Zone from Sonic the Hedgehog, with a custom titleset (WiP) I'm planning on recreating all 3 acts. I would love some help, as I'm a beginner and I want the level to be as good as possible (Editing the background textures, replacing music, object textures...)
Here are some screenshots, what do you think?
It's being made with Miyamoto

BTW, you should make a secret exit in Act 2, which can access Sonic Mania's Act 2. Basically:

Normal Exit=Sonic 1 act 3
Secret Exit=Sonic Mania act 2

Old 3DS XL info:
I used to have a 3DSafe A9LH V11.3.0-36U with Luma in my CTRNAND. Since ReiNAND Reibooted and Re-Reileased, I "switch"ed back.
Right now, I have boot9strap with Luma 8.0 as my CFW. Though, I'd like to see other CFW's for B9S.

That's a very good idea! Now I must figure how to recreate the atmosphere of that level, maybe I'll need some help making a completely custom titleset, as the one I'm using is actually a 1-1 titleset reskin. Now i think about recreating Manía, maybe I could even recreate Sonic Forces' Green Hill too, as it's desert themed and would add some nice diversity
